# Microsoft Flight Simulator — Intel Core i7-14700KF + NVIDIA GeForce RTX 4070 Ti SUPER

This combination of Intel's 20-core Core i7-14700KF and NVIDIA's 16 GB RTX 4070 Ti SUPER produces a fascinating scaling pattern in Microsoft Flight Simulator, one that reveals a workload heavily influenced by both CPU simulation overhead and GPU rendering limits. The measured data spans three resolutions and four settings presets, with average frame rates ranging from a demanding 61.5 FPS at 4K Ultra to a fluid 197.1 FPS at 1080p Low. The relationship between resolution, settings, and frame rate is anything but linear, and the implications for what limits this simulator are worth investigating.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep, but the trajectory depends almost entirely on the settings preset. At the Low preset, performance falls from 197.1 FPS at 1920x1080 to 153.3 FPS at 2560x1440, then to 111 FPS at 3840x2160. That represents a 23.7% reduction from 1080p to 1440p, followed by a 27.6% reduction from 1440p to 4K. The pattern suggests a growing GPU bottleneck as pixel count increases, yet even at 4K Low, the frame rate remains far above what most flight simmers would consider playable.

Moving to the High preset, the scaling becomes more aggressive. The 1080p result is 113.4 FPS, dropping to 92.1 FPS at 1440p (an 18.8% decline) and then to 64 FPS at 4K (a 30.5% decline from 1440p). The Ultra preset shows a similar shape: 108.1 FPS at 1080p, 89.1 FPS at 1440p, and 61.5 FPS at 4K. Notably, the gap between High and Ultra at 1080p is just 5.3 FPS, but at 4K it narrows to 2.5 FPS. This convergence implies that at 4K, the GPU is so heavily loaded that the difference between High and Ultra settings becomes almost irrelevant to the final frame rate.

The Medium preset sits between these extremes, with 148.9 FPS at 1080p, 120.3 FPS at 1440p, and 90.9 FPS at 4K. What is curious is that the percentage drop from 1080p to 4K for Medium (38.9%) is larger than for Low (43.7%) but smaller than for High (43.6%) and Ultra (43.1%). The uniformity of these 4K-to-1080p drops — all hovering around 40-44% — suggests that resolution scaling is dominated by pixel throughput rather than any single settings-specific effect. The data implies that at 4K, the RTX 4070 Ti SUPER's 672.3 GB/s of memory bandwidth and 44.10 TFLOPS of FP32 compute are the primary constraints, while at 1080p, the CPU's simulation thread becomes the more visible limiter.

GPU Role

The RTX 4070 Ti SUPER brings 16 GB of GDDR6X memory across a 256-bit bus, with a boost clock of 2610 MHz and a base clock of 2340 MHz. In a simulator like Microsoft Flight Simulator, which streams vast terrain and photogrammetry data, the 16 GB capacity is likely a key reason why the 4K Ultra result stays at 61.5 FPS rather than collapsing into single digits. The memory bandwidth of 672.3 GB/s, combined with the 45,900 million transistors on the AD103 chip, provides enough headroom for high-resolution textures and draw distances.

The GPU's nearest rivals in the benchmark database include the NVIDIA CMP 50HX (0.7% faster average score) and the NVIDIA RTX A2000 (1.6% slower), but those are synthetic averages; in this game, the measured FPS tells the real story. The Ada Lovelace architecture's 66 RT cores and 264 tensor cores are nominally present, but Microsoft Flight Simulator's frame rates at 4K Ultra (61.5 FPS) versus 4K High (64 FPS) show that the GPU is already near its practical limit. The 3DMark Steel Nomad DX12 score of 5569 and the Passmark G3D score of 31811 place this GPU in the 86th percentile of all GPUs, yet the game's demands still push it to the edge at 4K.

Interestingly, the GPU's percentile rank (86) is lower than the CPU's (96), yet the frame rate data shows the GPU becoming the bottleneck at higher resolutions. The 16 GB frame buffer is generous, but the 256-bit bus width and 672.3 GB/s bandwidth are the likely limiting factors when moving from 1440p to 4K, especially at Ultra settings where texture streaming and shadow complexity increase.

FAQ

Q: Why does the frame rate drop so much from 1080p to 4K at Low settings?

A: At 1080p Low, the system achieves 197.1 FPS, but at 4K Low it falls to 111 FPS. This 43.7% reduction indicates that even with minimal graphics settings, the GPU's pixel throughput and memory bandwidth become the primary constraint at 4K, as the CPU has enough single-thread performance (6,290 in Cinebench R23 single-core) to feed the renderer.

Q: Is the CPU or GPU the limiting factor at 1080p?

A: The data suggests the CPU is more influential at 1080p. The difference between 1080p Low (197.1 FPS) and 1080p Ultra (108.1 FPS) is 89 FPS, but the scaling from 1080p to 1440p at Low is only 23.7%, implying the CPU's simulation and draw-call overhead cap performance before the GPU reaches its limit.

Q: How does the Ultra preset compare to High at 4K?

A: At 3840x2160, Ultra averages 61.5 FPS while High averages 64 FPS, a difference of just 2.5 FPS (3.9%). This tiny gap indicates that at 4K, the GPU is saturated, and the extra fidelity from Ultra settings comes at almost no measurable frame rate cost.

Q: What is the best resolution for a consistent 60+ FPS experience?

A: All 12 measured configurations exceed 60 FPS on average. The lowest result is 61.5 FPS at 4K Ultra, meaning a user can run the game at maximum resolution and settings while staying above the 60 FPS threshold, though there is no margin for drops.

Q: Does the 16 GB VRAM help at 4K?

A: The 16 GB GDDR6X frame buffer is likely why 4K Ultra stays above 60 FPS. With 672.3 GB/s bandwidth, the GPU can stream high-resolution textures without stutter, as evidenced by the consistent average FPS across all four settings at 4K.

Q: How does this combo rank among all tested combinations?

A: In the database of 1,795 tested CPU-GPU combos for Microsoft Flight Simulator, this pairing ranks 184th, placing it in the top 10.3% of all combinations, which is consistent with the high CPU percentile (96) and GPU percentile (86).

Measured FPS Breakdown

At 1920x1080, the Low preset delivers 197.1 FPS, Medium drops to 148.9 FPS, High falls to 113.4 FPS, and Ultra bottoms out at 108.1 FPS. The step from Low to Medium is a 48.2 FPS reduction, while Medium to High costs 35.5 FPS, and High to Ultra only 5.3 FPS. This diminishing gap suggests that beyond High, the CPU's simulation thread becomes the limiting factor, as the GPU still has headroom at this resolution.

Moving to 2560x1440, the results are 153.3 FPS (Low), 120.3 FPS (Medium), 92.1 FPS (High), and 89.1 FPS (Ultra). The drop from 1080p is more pronounced at Low (43.8 FPS) than at Ultra (19 FPS), reinforcing that lower presets are more GPU-bound at higher pixel counts. The Medium preset at 1440p (120.3 FPS) is actually faster than High at 1080p (113.4 FPS), indicating that resolution alone does not dictate performance; settings complexity matters more.

At 3840x2160, the frame rates compress: Low runs at 111 FPS, Medium at 90.9 FPS, High at 64 FPS, and Ultra at 61.5 FPS. The spread from Low to Ultra is 49.5 FPS, compared to 89 FPS at 1080p. This compression is the clearest evidence of a GPU bottleneck at 4K, where even the lowest settings cannot fully escape the pixel throughput limit. The High-to-Ultra gap at 4K is just 2.5 FPS, making the Ultra preset effectively free in terms of performance.

CPU Role

The Intel Core i7-14700KF is a 20-core, 28-thread processor with a base clock of 3.40 GHz and a boost clock of 5.60 GHz. Its Raptor Lake-R architecture, built on Intel's 10 nm process, delivers a Cinebench R23 multi-core score of 44,557 and a single-core score of 6,290. In Microsoft Flight Simulator, which is known for heavy single-threaded simulation logic, the 5.60 GHz boost clock is likely the key driver of the high frame rates at 1080p Low (197.1 FPS). The CPU's 33 MB of shared L3 cache and 2 MB per-core L2 cache help reduce memory latency for the game's terrain and AI calculations.

The CPU's nearest rivals in the benchmark database include the Intel Core i7-14700K (0% delta), the AMD EPYC 9115 (0.3% faster), and the AMD Ryzen 9 9950X (0.4% slower). These near-identical scores (70,074 to 70,420 average) suggest that the 14700KF's performance is not exceptional among top-tier chips, yet its 96th percentile ranking among all CPUs means it is more than sufficient for this simulator. The data shows that at 1080p, the CPU is the limiting factor for the Low preset — the 197.1 FPS result likely approaches the simulation's update rate — but at higher resolutions, the GPU takes over as the bottleneck.

The Passmark multi-thread score of 52,425 and single-thread score of 4,480 indicate strong overall compute, but the game's frame rate at 1080p Ultra (108.1 FPS) versus 1080p Medium (148.9 FPS) suggests that the CPU cannot fully utilize the GPU's potential when settings are lowered. This is a classic CPU-bound scenario, where the simulation thread becomes the ceiling.

Settings Recommendations

The measured data offers a clear hierarchy for this combo. At 1080p, the Medium preset (148.9 FPS) provides a 31.3% improvement over High (113.4 FPS) while still delivering a visually rich experience; the jump from Medium to Low adds 48.2 FPS but sacrifices significant fidelity. For users with a 144 Hz monitor, Medium at 1080p is the best match, as it exceeds 144 FPS, while High (113.4 FPS) falls short. At 1440p, the Medium preset (120.3 FPS) is the sweet spot for high-refresh displays, while High (92.1 FPS) is ideal for 90-100 Hz panels. The Ultra preset at 1440p (89.1 FPS) offers no meaningful advantage over High in frame rate terms but adds graphical overhead.

For 4K, the recommendation is more nuanced. The High preset (64 FPS) and Ultra preset (61.5 FPS) are nearly identical, so choosing Ultra is essentially free and provides the best visual quality. The Medium preset (90.9 FPS) is the best choice for a 90 Hz display, while Low (111 FPS) suits 100+ Hz panels but sacrifices terrain detail. Given the game's genre, where immersion matters, the Ultra preset at 4K (61.5 FPS) is the most compelling option because the 2.5 FPS cost over High is negligible. The data indicates that this combo can handle 4K Ultra at an average above 60 FPS, which is a playable baseline for flight simulation.

How This Combo Ranks

In the database of 1,795 tested CPU-GPU combinations for Microsoft Flight Simulator, this pairing of the Intel Core i7-14700KF and NVIDIA GeForce RTX 4070 Ti SUPER ranks 184th. That places it in the top 10.3% of all combos, a strong showing given the game's demanding nature. The CPU's 96th percentile ranking (among all CPUs) and the GPU's 86th percentile (among all GPUs) combine to produce a system that is well-balanced for this workload, though the rank suggests there are 183 combinations that achieve higher frame rates.

The rank implies that while this combo is excellent, it is not at the absolute top tier. The GPU's nearest rivals — the NVIDIA CMP 50HX and RTX A2000 — are not gaming-focused cards, yet their similar average benchmark scores (49,071 and 47,915) highlight that the RTX 4070 Ti SUPER's performance is competitive but not dominant. The CPU's rivals, including the Ryzen 9 9950X and EPYC 9115, show that the 14700KF is in a tight performance cluster where no single chip has a decisive edge. For players seeking higher ranks, the data suggests that a faster GPU would yield more gains than a faster CPU, given the GPU bottleneck observed at 4K. Conversely, at 1080p, the CPU's single-core performance (6,290 in Cinebench R23) is already sufficient, so the 184th rank is more a reflection of GPU limits at higher resolutions than any CPU deficiency.
